Public bug reported:
There seems to be a bug somewhere in [ kernel OR xorg OR nvidia proprietary
driver ] in the display stack.
After the laptop ( dell XPS L501X ) resumes from suspend there are wide black
borders around all windows with close/minimize/maximize buttons blacked out.
[ image attached: black border on all windows ]
It occurs inconsistently, as it doesn't happen every time the computer resumes.
( Slight possibility that it usually occurs after long suspend, i.e. resuming
after long time ).
=================================================================================
Also there seems to be certain amount of performance degradation as if
the graphics driver was running at half-strength ( and I don't mean
software-only rendering, neither do I mean switch over to nouveau open
source driver )
The "nVidia X Server Settings" app suggests its in maximum performance
mode.
==================================================================================
Adhoc Workaround: switch display layout ( I have an external monitor/TV
attached to HDMI port ) changing anything such as arrangement or
resolution of the displays, etcetera... corrects the black border issue
( and also possibly performance issue )
This bug has been present in Ubuntu 14.04, 15.04, 15.10 and now in 16.04
as well. ( It was probably present before that as well )
==================================================================================
p.s. this is only partial duplicate of black border issue as the black
borders appear on every window, not just windows with new header bars or
client side decoration...
